multi-center, double-blind, randomized, placebo-controlled study of the safety and efficacy.

Phase

Chronic Fatigue SyndromeMyalgic Encephalomyelitis

Drug: Ampligen

Phase 3

Detailed Description:

This study will be a prospective, double-blind, randomized, placebo-controlled, equal parallel groups study conducted at up to fifteen (15) centers to compare the safety and efficacy of Ampligen® IV versus placebo IV in 230-240 patients with CFS/ME. Patients will be randomized and stratified to receive either Ampligen® intravenously or placebo (normal saline) intravenously. Fifty percent (50%) of the patients will be treated with Ampligen® IV and 50% of the patients will be treated with placebo IV.

Patients will be studied until 64 weeks (STAGES I plus II) have passed or until: 1) removed because of toxicity, 2) they withdraw voluntarily, 3) a change in the patient's medical condition makes continued participation unsafe, 4) the patient becomes non-compliant with the requirements of the protocol or 4) the Sponsor terminates the study.

Criteria

Inclusion Criteria:

A diagnosis of CFS, as defined by the Center for Disease Control (1988 CDC case definition) > 12 months (Appendix D).

Age Range: > 18 years old, < 60 years old.

Males or non-pregnant, non-lactating females: Females must be of non-child bearing potential (either post-menopausal for two (2) years or surgically sterile including tubal ligation) or using an effective means of contraception (birth control pills, intrauterine device, diaphragm). Females who are less than two (2) years post-menopausal, those with tubal ligations and those using contraception must have a negative serum pregnancy test within the two (2) weeks prior to the first study medication infusion. Females of child bearing potential agree to use an effective means of contraception from four (4) weeks prior to the baseline pregnancy test until four (4) weeks after the last study medication infusion.

A reduced quality of life as determined by a documented KPS of 40 to 60 on three (3) occasions, each at least 14 days apart, during the twelve (12) weeks immediately preceding the start of study drug infusions. The KPS must be rounded in increments of ten (10).

Laboratory documentation (baseline or historical following onset of CFS/ME) of a negative ANA or a negative anti-ds (double-stranded) DNA, a negative Rheumatoid Factor, and an erythrocyte sedimentation rate (ESR).

Laboratory documentation that the patient is euthyroid (patients on thyroid replacement therapy must be on a stable dose during the eight (8) week washout period) based on a thyroid profile (T4, T3, TSH, T3 uptake and Free T4 index) performed during baseline.
